After I purchased Funguys Swarm, copied the code, and entered it into Coral Island, I received an "Invalid Key" message.
I haven't received the item yet.
I've tried various methods.
Re-login to Steam >> When I redeem the code, it still says "Invalid Key."
Re-install Funguys Swarm >> When I redeem the code, it still says "Invalid Key."
Re-install Coral Island >> When I redeem the code, it still says "Invalid Key."
Can you help me investigate this issue?
Thank you very much.
